Description

Technical Field

[0002] In order to strengthen the operation and maintenance quality of the medium-voltage distribution network, realize the professionalization and refinement of distribution production management, and greatly reduce the average power outage time of customers, it is necessary to effectively carry out ground potential live operations to achieve controllable and re-controllable average power outage time for customers throughout the year, further improve planned non-stop operations, and enhance power supply reliability and customer satisfaction.

[0003] The existing method of connecting the three-phase power lead wires is to connect the three-phase power wires in sequence, that is, first connect one of the lead wires to the wire of one phase, then connect another lead wire to the wire of the second phase, and finally connect the third lead wire to the wire of the remaining phase; among them, the single-phase connection process is to first fix the lead wire on the wire clamp, and then fix the wire clamp on the single-phase wire; however, after the first phase lead wire is connected, due to the existence of the phase-to-phase capacitance, a capacitive coupling voltage will be generated on the other two phases of non-energized lead wires. If a transformer is connected to the end of the connected lead wire, a voltage will be induced in the other two lead wires through the transformer winding. When the latter two phase lead wires are connected, there is a risk of human body being connected to the circuit. Summary of the Invention

[0036] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0037] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0038] Secondly, the term "one embodiment" or "embodiment" herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in various places throughout this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive of other embodiments.

[0039] Example 1, reference Figure 1-9 , which is the first embodiment of the present invention, provides a circuit bonding device for live working in a distribution network, comprising an insulating rod group 100, and a wire clamp assembly 200 provided on the insulating rod group 100;

[0040] The insulating rod assembly 100 includes a main rod 101, a hook 102 is provided on the main rod 101, a first auxiliary rod 103 is provided on one side of the main rod 101, and the wire clamp assembly 200 is detachably mounted on the first auxiliary rod 103;

[0041] The insulating rod group 100 is used for operation by splicing personnel so that the splicing personnel do not need to directly contact the wires and drainage wires, thereby preventing the human body from being inserted into the circuit.

[0042] The wire clamp assembly 200 includes a base 201 detachably arranged on the first secondary rod 103, with a secondary wire hole 202 and a main wire hole 203. The lower end of the main wire hole 203 is provided with an opening 204, and a sealing plate 205 is provided at the opening 204.

[0043] The wire clamp assembly 200 is used to fix the drainage wire and the electric wire so that the drainage wire and the electric wire are connected to achieve overlapping drainage.

[0044] The specific splicing process is: first fix the three drain wires in the auxiliary line holes 202 of the three splicing devices respectively, and then hang the three splicing devices with the drain wires fixed on the three wires of the three-phase electricity through the hooks 102 respectively, and then perform single-phase splicing. During single-phase splicing, remove the splicing device hanging on one of the wires, and fix the wire in the main line hole 203 of the corresponding splicing device through the sealing plate 205, and then remove the insulating rod group 100 to complete the splicing of the phase, and use the upper single-phase splicing process to complete the splicing of the remaining two phases in turn. During the upper operation, hold the main rod 101 to hang the splicing device on the wire or remove it from the wire. When removing the insulating rod group 100, separate the first auxiliary rod 103 and the base 201 to remove the insulating rod group 100.

[0045] When the splicing device of the present application is used for splicing, since the three drain wires are pre-fixed on the wire clamp assembly 200, there is no need to perform the drain wire fixing operation during the subsequent single-phase splicing process, thereby avoiding the risk of the human body entering the circuit when the drain wires are fixed when the next two phases are spliced ​​after one phase is spliced; at the same time, due to the setting of the main pole 101 and the first sub-pole 103, the two have different divisions of labor. The main pole 101 is used to hang the entire device on the wire, and the first sub-pole 103 is used to support the wire clamp assembly 200 after the drain wire is fixed, preventing the wire clamp assembly 200 after the drain wire is fixed from hanging down arbitrarily, thereby avoiding the splicing personnel from touching the base 201 and the drain wire during operation, further reducing the risk of the human body entering the circuit.

[0046] Furthermore, the insulating rod group 100 also includes a connecting member 104 arranged between the main rod 101 and the first sub-rod 103, and the connecting member 104 includes a connecting rod 104a, and both ends of the connecting rod 104a are provided with a clamp 104b, and the clamps 104b at both ends of the connecting rod 104a are respectively mounted on the outside of the main rod 101 and the first sub-rod 103.

[0047] The connecting piece 104 connects the main rod 101 and the first auxiliary rod 103 into a whole. The connecting piece 104 is fixed together with the main rod 101 and the first auxiliary rod 103 through the clamp 104b, which is convenient for assembly and disassembly.

[0048] Furthermore, the wire clamp assembly 200 also includes a first screw rod 206 vertically arranged on the base 201 , the upper end of the first screw rod 206 passes through the auxiliary wire hole 202 , and the lower end of the first screw rod 206 is threadedly connected to the first auxiliary rod 103 .

[0049] The function of the first screw rod 206 is that after the drainage line passes through the secondary line hole 202, the first screw rod 206 presses the drainage line tightly into the secondary line hole 202, while ensuring the effective contact area between the drainage line and the base 201, avoiding the heating problem caused by the small contact area; on the other hand, the first screw rod 206 is also used to connect the base 201 and the first secondary rod 103. Specifically, the top of the first secondary rod 103 has a threaded hole, and the lower end of the first screw rod 206 is threadedly connected to the threaded hole. When the insulating rod group 100 is removed from the base 201, the first secondary rod 103 is rotated to separate the first secondary rod 103 and the first screw rod 206.

[0050] In order to prevent the first sub-rod 103 from being rotated and removed from the first screw rod 206, which will cause the first screw rod 206 to loosen its fixation on the drainage wire, the force exerted on the first screw rod 206 when the first sub-rod 103 is rotated is in the same direction as the rotational force required to twist the first screw rod 206 upward; in addition, in order to prevent the main rod 101 from affecting the rotation of the first sub-rod 103, after the connecting device is removed from the hanging wire, the corresponding clamp 104b can be loosened to remove the main rod 101.

[0051] Furthermore, sliding grooves 207 are provided on both sides of the opening 204, and the closing plate 205 is slidably provided between the sliding grooves 207 on both sides of the opening 204. A second screw rod 208 is vertically provided on the closing plate 205, and the upper end of the second screw rod 208 passes through the main line hole 203, and the lower end of the second screw rod 208 is provided with a connecting part 209.

[0052] The wires enter the main wire hole 203 from the opening 204, and then the sealing plate 205 is installed at the opening 204 to block the opening 204 to prevent the wires from falling out of the main wire hole 203; the base 201 is specifically connected to the sealing plate 205 through a sliding groove 207, thereby blocking the main wire hole 203; the second screw rod 208 on the sealing plate 205 is used to tighten the wires in the main wire hole 203, ensuring the contact area between the wires and the base 201, and avoiding heating problems caused by the small contact area.

[0053] Furthermore, the insulating rod group 100 also includes a second auxiliary rod 105, the upper end of the second auxiliary rod 105 is provided with a connecting hole 106, and the connecting part 209 at the lower end of the second screw rod 208 is inserted into the connecting hole 106; the connecting part 209 is hexagonal, and the shape of the connecting hole 106 is adapted to the connecting part 209.

[0054] Of course, the first screw rod 206 , the second screw rod 208 , the sealing plate 205 and the base 201 are all conductors.

[0055] After the wires are placed in the main wire hole 203, the second auxiliary rod 105 is specifically used to install the sealing plate 205 in the sliding groove 207 of the opening 204; specifically, the first auxiliary rod 103 is held by hand to drive the wire clamp assembly 200 to move, so that the wires enter the main wire hole 203 from the opening 204, and the connecting portion 209 at the lower end of the second screw rod 208 is placed in the connecting hole 106 of the second auxiliary rod 105. At this time, the sealing plate 205 is placed on the upper part of the second auxiliary rod 105 through the second screw rod 208, and then the second auxiliary rod 105 is held by hand to slide the sealing plate 205 into the sliding grooves 207 on both sides of the opening 204 to achieve the installation of the sealing plate 205; at the same time, The second sub-rod 105 and the second screw rod 208 are connected by the adaptive hexagonal prism-shaped connecting part 209 and the connecting hole 106, so that the rotation of the second sub-rod 105 can drive the second screw rod 208 to rotate. After the sealing plate 205 is installed, the second sub-rod 105 is rotated to drive the second screw rod 208 to rotate, so that the second screw rod 208 pushes the wire upward to the top, and then the second screw rod 208 is removed; in order to prevent the connecting part 209 from detaching from the connecting hole 106 during operation, the aperture and shape of the connecting hole 106 are consistent with the outer diameter and shape of the connecting part 209, and the connecting hole 106 has a certain depth and the connecting part 209 has a corresponding length.

[0056] Example 2, reference Figure 1-9 , which is the second embodiment of the present invention, is different from the previous embodiment in that the insulating rod set 100 further includes a clip 107 arranged on the inner side of the hook 102, and there are two clips 107, with a gap between the two clips 107.

[0057] Furthermore, the clips 107 are arc-shaped, the openings 204 of the two clips 107 are arranged in opposite directions, and the clips 107 are elastic members.

[0058] When the entire splicing device and the drain wire are hung on the electric wire through the hook 102, the two clips 107 on the inner side of the hook 102 clamp the electric wire to prevent the device from shaking or even falling.

[0059] Example 3, reference Figure 1-9 , which is the third embodiment of the present invention, is different from the previous embodiment in that the method for connecting the circuit connecting device for live working on the distribution network includes the following steps:

[0060] Take three splicing devices and fix the three drainage lines in the secondary line holes 202 of the three splicing devices respectively;

[0061] Hang the three bonding devices on the three wires of the three-phase power distribution network respectively;

[0062] Remove one of the splicing devices, place the corresponding wire into the main line hole 203, and seal the opening 204 with the sealing plate 205, then remove the insulating rod group 100 to complete the splicing of the phase wire;

[0063] Remove another splicing device, fix the corresponding wire in the main wire hole 203 of the splicing device, remove the insulating rod group 100, and complete the splicing of the phase wire;

[0064] Remove the last splicing device, fix the last phase of the wire in the main line hole 203 of the splicing device, remove the insulating rod group 100, and complete the splicing of the last phase of the wire.

[0065] Furthermore, the connecting device is hung on the corresponding electric wire via the hook 102 .

[0066] Specifically, first fix the three drainage lines in the auxiliary line holes 202 of the three connecting devices respectively, and tighten them through the first screw rod 206;

[0067] Then hold the main pole 101 and hang the hooks 102 of the three connecting devices on the three wires of the three-phase electricity respectively;

[0068] Single-phase drainage splicing: Hold the main rod 101, remove one of the splicing devices, then hold the first sub-rod 103, remove the main rod 101 of the splicing device, hold the first sub-rod 103 to drive the base 201 on it to move, so that the corresponding wire enters the main line hole 203 from the opening 204 of the base 201, then hold the second sub-rod 105, slide the sealing plate 205 into the sliding groove 207 on both sides of the opening 204, and block the main line hole 203, then rotate the second sub-rod 105 to make the second screw rod 208 press the wire tightly, then remove the second sub-rod 105, and then rotate the first sub-rod 103 to remove the first sub-rod 103 from the base 201 to complete the single-phase drainage;

[0069] Repeat the single-phase drainage overlap operation in sequence to complete the overlap drainage of the remaining two phases.

[0070] During the three-phase electrical splicing process, since the three drain wires are pre-fixed on the wire clamp assembly 200, there is no need to perform drain wire fixing operations during the subsequent single-phase splicing process, thereby avoiding the risk of human body entering the circuit when the drain wires are fixed when the next two phases are spliced ​​after one phase is spliced.
